Submarine STEM KS2: How do you recover a submarine with levers and pulleys?

This is the sixth in a six lesson unit, Submarine STEM KS2. We reccomend that you take students on the journey of levers using both lesson five and six. Lesson six sees students develop their understanding of levers and pulleys and relates this to how cranes launch and recover submersibles. Students will continue to develop their crane, this time adding a lever or pulley system which will raise and lower their submarine model. This lesson is from the Submarine STEM 7-11 unit.

The unit enables students to explore materials, forces, and living things while working scientifically. The unit is based on real life submersible exploration of the XL Caitlin Deep Ocean Survey off Bermuda, the Sargasso Sea. To experience the full impact of this scheme of work it can be taught in advance of our annual Submarine Live event. Live lessons can be booked for free here: https://encounteredu.com/live
